Nothing i can think of after 2 weeks of extensively use. The batteries hold the charge and deliver the power needed on demand, what more to say? There are LiFePO4-batteries outside with a higher capacity, but at the expense of a very higher price. This battery simply delivers the power promised for a more than reasonable price. This is simply a very good bang for the buck - get it, if you need it! Read more

Long lasting and so far I have recharged it several times with no loss of life. The spare sat in the drawer for six months and still held a strong charge! Power output was as advertized. None, nada, zip. It's a battery, it either works or does not, or doesn't perform as advertized. These did. It...Long lasting and so far I have recharged it several times with no loss of life.

The batteries are protected and therefore will not overcharge or burn or anything else that happens when batteries are overcharged. The runtime with item 90601 I could not test yet but it is certainly above an hour.

The runtime with item 90601 I could not test yet but it is certainly above an hour. The batteries are longer than you might expect but this should be fine as you buy it because you need it. Maybe a bit long, I used it in sku 90601 and the end of the battery was dented. This is maybe the only con of the battery. It could also be a con of the flashlight. It is a great a battery, you get two. The price is well worth for what you get, the runtime is great and they look good as well. Where else will you find blue batteries?! Buy it if you need 18650 batteries, you cannot go wrong with this. Read more

I've bought 4 items (2pack) to repair my no-name accu drill - I wanted to substitute old NiCd 12V pack with 2P4S pack of this LiFePo. Work perfectly, real capacity 1200mAh/cell measured by Orbit Pocketlader, 4A output without any noticeable heating. After 1 month of everyday using no capacity No...I've bought 4 items (2pack) to repair my no-name accu drill - I wanted to substitute old NiCd 12V pack with 2P4S pack of this LiFePo. Work perfectly, real capacity 1200mAh/cell measured by Orbit Pocketlader, 4A output without any noticeable heating. After 1 month of everyday using no capacity losses. No cons, really :) may by price could be slightly lower, and I will buy another 4 packs Must use specific charger, max. voltage 3.65V per cell. Great for hobby and home use, just try it - buy this 2pack instead of single one Read more

- high amp (4.5amp), with 10 of these maybe you can turn your car on :P
- blue hehehe
- right voltage for laser addicted (3.2v)

- LiFePO4 (no need to say more) - somehow get discharged faster than Li-Ion, but it is common to LiFePO4.
- hard to connect in series, both sides are flat.
- hard to find a charger, but one can be home-made. - never insert a spring if you are going to use 4 amps, it will heat the spring and melt the plastic side of the cell (look my photos) very good and useful.
Deal class: HOT! (4.5/5) Read more

regarding the con: on the anode it has 4 holes, where you can put a spring for putting the cells on series for diy.
fully compatible with many flashlights, etc...

mine came with 4.27v with 4.60amp. don't have the bigger tip on the anode, being hard to use 2 cells on series, on diy projects (not really a con)
lasts half the time of a common 18650, but it is not a con, it is a disadvantage of the LiFePO4.
NO CONS! I had to built my own charger for these batteries, hard to find a cheap smart charger. buy it ! can even replace two AA cells (on some devices that could use 3.6~3.2 instead of 2.6~3v) Read more

Cheap, robust, end pins solder easily. none that i can think of! Using these as primary power pack on my Honeybee king 2. Very impressed! get about a 5 minute flight time.

Using these as primary power pack on my Honeybee king 2. Very impressed! get about a 5 minute flight time. Initial charge led to the cells not balancing, but with each subsequent charge balancing and storage improved. Even though these are not supposed to be high discharge rate cells, they give plenty of power throughout the lifespan of the charge! Quite a surprise as they measure up quite well next to my a123 packs which cost about triple the bucks! Buy them up guys!!! Read more

it works. its blue hehee whats to say ???
its cheap. get it if you need it.
could be nice if it came in a plastik holder.
but i have ordered some from this page. so no problem.. well maybe it is the light. but it seems to loose power fast. but it might be my flashlight i dont know.

The capacity very close to declared - mine IMax B6 shows 1230-1250mAh at 1A discharge current (discharger is not able to consume less than 1A).

Fast recharge (about 30 min) ability
Easily to solder conclusions. Low current at discharge (4C only) - LiFePo4 accu's by &quot;A123 cells&quot; give me up to 10C
Price may be lower, at all... Good battery for mid-current operation, fast-rechargable, user friendly, safe.
Seems like to good idea use it in electric scooters I will buy more, quality suits me! Read more
